"Druknet i Leppa? Elv ved Tømmerbrøtning, og igjenfunden i Ona? Elv den 13 Juli."
He drowned in the Leppa? river while clearing a logjam, and was refound in the Ona? river on 13 July. I'm not familiar with the river names, and it's not made better by the cutting of the page.
Log driving was dangerous work, and many of my relatives perished in the same way.
